The Ruth Bitting Hamm Digital Library
The Genealogical Society of Pennsylvania welcomes you to explore the collections housed in the Ruth Bitting Hamm Digital Library, named to honor a family historian and benefactor of several genealogical and historical organizations nationwide.
Search over 200 collections in the Member Collections and Public Collections and Resources. We also have several manuscript collections and other collections that are not yet listed online. The GSP Library Catalog has over 1200 books held by the library of The Genealogical Society of Pennsylvania.
Our GSP digital newsletter, the Pennsylvania Genealogical Magazine (1948-2015), the Publications of the Genealogical Society of Pennsylvania (1895-1947), and our previous newsletter, Penn In Hand, are online for GSP members through our Publications page. A few remaining volumes of PGM are still being added to the website.
